Making Microchips at Home - Cooking with Jeri Part1

I show how to cleave wafers, remove native oxide, test the dopant type with a hot probe test and loading the furnace.

can we use this tecniques to make a solar cell?

@jeriellsworth About 1.2um ideally.

@ngneer999 I'm running oxidation for 6hrs. I have extra tubes for mine if I wanted to keep dopants separate. I don't at the moment.

[ngneer999]

I'm running a very similar oxidation furnace right now and really it's not much more sophisticated. It has boiling water and 1000C. Don't allow dopants or metals in mine though. How long did you run your oxidation? I'm running 17.5 hours for about 2um. Also note that I'm not scolding you about the HF.

@Racius19 I get the wafers from ebay.

@cpypcy Education, hobby, etc. What is the use for making anything at home that can be done better in mass production?

[cpypcy]

What's the use for home made microchips?

[Racius19]

Where did you get a waffer ? I work in layout for ON Semiconductor in Czech Republic and they refused giving me old, scratched, smudged representative waffer samples argumenting that it is protected by trade secret :)

But anyway, your work is great, I was wondering about making my home-made semiconductor parts and now, I feel determinedly for it :)

@RussellTuan It's not luck. You should watch my other videos where I show working devices. I've made functional devices for the last 3 years.

as a former equipment engineer of mass production of semiconductor,i solute to you.good luck!!
